; Gravitomagnetism consists of Newtonian;gravity and gyrotation, which is totally;analogous to magnetism. In an earlier paper;I suggested that the attraction between elementary particles;(trapped light) is generated by a Coriolis effect between gravitons and;particles (Coriolis Gravitation Theory). In the subsequent paper, I deduced that the;amplitude of gravity between particles is ruled by the spin-orientation;of particles;and I explained the origin of the Expanding;Earth. Here, I consider the consequence that the value of the;gravitational;constant of the Sun is ruled only by the number of like-oriented;particles in;the Sun and in the planets. I find that the lifecycle of stars is ruled;by a gravitomagnetic;cycle.
